Hi :)

Completed upto Step 3 and am now stuck on Step 4 :(

Can someone now lead me by holding my finger ...

Ok, so I downloaded su-2.3.6.1-ef-signed.zip and put it in the platform-tools folder

I powered on my sns ... and I see a picture of a Lock that was never there before.

I tap the screen and I get those Gingerbread startup flares ... or whatever one calls it!

I then get the "Turn on USB Storage" button

is it at this stage that I Type "adb push su-2.3.6.1-ef-signed.zip /sdcard/su-2.3.6.1-ef-signed.zip" & hit enter?

or do I actually turn on USB storage and then run that command?

Either way I get the error: device not found.

Am kind of scared now ... will all be ok?

Thanks for any help :)
[Nexus S General] thiagodark:
forget about adb, just turn on usb storage and copy, through file manager in you PC, the su file (su-2.3.6.1......) to the sd card of your device and jump to the step 7: "Boot the SNS into the Bootloader Interface, by holding Volume UP & Power button"
[Nexus S General] Paparasee:
Thanks thiagodark ... really appreciate all sorts of help :)

I booted normally into my phone SNS 2.3.4 I9020 and then tuned on USB Storage. That done, I copied the file su-2.3.6.1-ef-signed.zip to the root of my sdcard (or whatever one calls similar memory on the Nexus S.

I then turn off my phone, and (7) boot up by pressing Volume up and Power button as suggested by you.

Next, I do (8) ... using vol down key I select "Recovery" and press the power button.

Now I get the lil droid with the ! (exclamation mark).

I press power and volume up and get blue screen that says "Android system recovery <3e> ... options here are:

reboot system now

apply update from /sdcard

wipe data/factory reset

wipe cache partition

I presume I have to choose apply update from /sdcard so I use volume down and hit the power key.

now I choose "su-2.3.6.1-ef-signed.zip" which is on the root and hit the power key again!

I now get .... (in yellow)

-- Install /sdcard ...

Finding update package...

Opening update package...

Verifying update package...

E:signature verification failed

Installation aborted.

:( where did I go wrong? I got the SU file from [APP] Superuser 2.3.6.1 - Now on the Market [2010-09-05] ... the link above ... it was about 289/290 kb
[Nexus S General] thiagodark:
"

paparasse, when you select "recovery" in bootloader and you get the android recovery (triangle with exclamation mark), it's because you didn't flash clockworkmod recovery... stock recovery won't install su file.

so, or you skipped "part 3" or you can't reboot after flash it

did you unlock bootloader? (do you see the a open paclock bellow "google" in the first screen?) if YES, repeat step 3:

1 - Download the ClockworkMod recovery image (for i9020A models, use this i9023 recovery image too!) 3024v3-i9023.img from [MOD][RECOVERY]Clockwork 3.0.2.4 New wipe & confirm menus!! i9023 & i9020 versions

2 - Save it to the Android SDK "tools" dir

3 - Open a command prompt go to run & type "CMD" & hit enter

4 - Switch to the directory where you unzipped the Android SDK & go to "tools"

5 - Then type "fastboot flash recovery 3024v3-i9023.img" & hit enter

and after all DON'T TURN OFF your phone, select "recovery" instead! you should see clockworkmod recovery (not android recovery), like the image bellow (but in another version, of course):

then, you follow from step 10: "Select "Install ZIP from sdcard" (power button to apply)"

hope it helps
[Nexus S General] BeddyTear:
Thanks thiagodark for your helpful advice from the two posts - #310 and #313. That file and advice to just skip to step 7 made rooting the Nexus S a breeze. Thanks again. :)
[Nexus S General] thiagodark:
no problem, everytime i need help, someone helps me, so i do what i can helping others! =o)

i really think this guide could be updated, it can be a lot easier, and as many people following this guide are 'noobs', it would be very useful.

but i guess op is not very active in the forum...
[Nexus S General] Paparasee:
thiagodark ... that really helped .... Really appreciate your help in leading me through this :)

I had completed step 3 but ... as mentioned in step 3 of the original guide, I had rebooted the phone and hence was not able to get to the intended screen. So I guess the line below pointed by you is crucial!

Am rooted now ... whatever that means :p now what??? :-/ ... guess I'll have to read more to understand stuff about flashing roms and whatever the other possibilities of a rooted phone!

One quick question ... would rebooting the phone make me lose my root or is it just that when I reboot I will not be get into CWM Recovery unless I go through step 3 again?

Wonder how I'd go about flashing roms ... guess I'll see you in another topic!

Thanks again! :)
[Nexus S General] thiagodark:
to keep cwm recovery you should rename the file in the folder /etc/install-recovery.sh to something else (like recovery-old.sh), then reflash cwm rocovery.

this file contains a script that rewrites stock recovery after a reboot, every single rom (or whatever else you can think), is made to be flashed in cwm recovery, but without stock recovery you won't be able to get ota updates.

just don't forget to make a nandroid backup (cwm -> backup), and save it in a safe place, before starting to play around! =o)

edit: one more thing: don't blame the guide, i believe the script file was introduced by 2.3.4 version, before it (when the op kindly wrote the guide) cwm sticked after reboots!

Hey guys i9020A here, having a problem when I connect either when my android is on (says Nexus S) or when it's in bootmode (says android 1.0) windows 7 won't recognize the driver and gives it's an exclamation point and I can't go farther down the list ;/. Any help would be appreciated!
[Nexus S General] zero383:
Right click > update drivers

Browse my compuer > let me choose > Have disk

Point to "android_winusb.inf", it's in the SDK package you should have installed

Uncheck show compatible devices > choose the bootloader one
[Nexus S General] wickedjoey:
I just fixed this before I read your post Zero383. I did what you said but for some reason before I didn't think of this >>. Thanks for the help though!

[Nexus S General] wickedjoey:
Everytime I get to this step

7 - Boot the SNS into the Bootloader Interface, by holding Volume UP & Power button

8 - Select "Recovery

Instead of going into recovery I get the exclamation mark on my screen and I have to pull out my battery. What am I doing wrong??
[Nexus S General] zero383:
That is the stock recovery and you don't need to take out the battery. You can access the menu by holding the power button then press up volume.

After flashing CWM DO NOT REBOOT THE PHONE. Go directly into recovery.
[Nexus S General] wickedjoey:
Thanks again Zero that was the reason. Now that I DL'd Rom Manger and Cynaogen mod I've been stuck at the loading screen for the past 5 mins with the little guy on a loop riding his skateboard. The arrow of the circle stops midway then resets.

Fixed it, had to wipe data. Well it's finally finished. This was a great and stressful experience, thanks for the help zero!
[Nexus S General] epichappy:
Hi,

I was wondering what is deleted when the boot loader is unlocked.

Will I loose my apps rooting my phone?

Thanks!
[Nexus S General] zero383:
Unlocking the bootloader will do a factory wipe on the phone. You will lose all your apps and data. I'm not positive but your SD storage contents may be wiped as well. I unlocked it right after I got my phone so I couldn't really check that.
[Nexus S General] EdForce1:
The SD card get's wiped too.

Certainly not a straightforward procedure in my experience, but i've managed to get it done in the end, and now my Nexus S is unlocked, rooted and ready to hit those custom ROMs! :)
[Nexus S General] tancer:
Very nice forums. Lots of altruism and help. I love it!

I want to root my Nexus 9020A from Telus. However here are some questions I still have after reading the entire thread.

1. I already have a lot of applications installed; I read about Nandroid and the fact that it is important to use it before rooting so that I don't lose everything. Is that correct?

2. I also read in the very recent replies that the walkthrough is somewhat complicated for nothing and that it could use an update; which part could be updated or do you have a better/simpler walkthrough to suggest me?

3. Finally, if I want to revert back to stock so I can update in the future the OS, which way is the easiest and/or what would you suggest to me concerning this?

Basically, you probably understood that I want to make sure I don't screw my phone, that I don't want to lose all my apps and that I want to have an alternative to go back to stock if anything goes bad.

Thanks to whoever reponds to this. It is extremely appreciated! :)
[Nexus S General] tizoune7401:
Thanks a lot to all of you guys for this great thread and now my ns is rooted
[Nexus S General] thiagodark:
1)the only way you can make a nandroid backup is by unlocking your bootloader and flashing cwm recovery, and to achieve it you will need to wipe everything. so, there is no way to root/flash roms/make nandroid backup and don't lose your apps.

2) atually i can see three parts in the walkthrough that can be some confuse (almost 100% of the questions here are related to that)

a)install usb drivers: to get through it, just look to the previous posts from zero

b)when the guide says to: "adb push su..." replace it by copying su file to sd card into your device, it's easier and noob proof! =o)

c) if your reboot the phone after flash cwm recovery, it will be replaced by stock one, so, don't reboot your phone after flash recovery, get in just after that..

3) to get back to stock, just flash the proper ota file from the thread sticked in general section.

good luck! =o)
[Nexus S General] tancer:
Thanks a lot for your advices! I will root my phone today, kind of anxious but we'll see how it goes :)

I'm sad though to see that I will lose every app i downloaded :(

I will keep you guys updated on the process. Again, thanks for your help Thia.

EDIT**

Do I also lose Google's factory apps? Like Google Music, Google earth, etc etc? Thanks!
[Nexus S General] thiagodark:
the phone goes back to factory setting, as you donwloaded earth and new music app from the market, they will be removed too, just install/update again. you will have market, so, no problem! =oP

now, i'm gonna back to formule 1, damn rain!!
[Nexus S General] tancer:
Ok!!

And I agree Montreal is where I live and I didn't go to the GP this year because of the weather forecast ;)
[Nexus S General] toxicdrift:
thank you! first post here and got my phone rooted :D
[Nexus S General] tancer:
NVM saw Zero's post 10 pages ago.
[Nexus S General] tancer:
Ok, so I installed the drivers but then it said that it timed out. Now, I see the android phone in the device manager BUT it does not read Android Bootloader Interface. Please help, my phone is still in bootloader, I didn't do nothing yet. Just install the drivers. I downloaded usbdeview but don't know how to use it/if it is of any use now.

Thank you, I hope to finish this soon :)
[Nexus S General] thiagodark:
i thanked you trying to quote! =oP

how is it shown in device manager?! you should to reinstall the device driver and pick bootloader one...

Yep. I've done it.

I cannot get my computer running windows 7 to recognize my 9020A from Rogers. I've used the driver cleaner program as suggested, and installed the android sdk/java SE, but still no go. I've skipped the part of the guide that asks to change the inf file (which it says I should skip -- for my model). Is that the problem?

Any tips would be appreciated.
[Nexus S General] thiagodark:
when you are in bootloader screen of your phone and plug it into pc, what did you see in windows device manager?!
[Nexus S General] Zorrich:
It attempts to find the driver, but then gives me a failed to install driver message. In the device manager, it shows android 1.0, but there is a question mark (or some form of yellow warning) next to it.
[Nexus S General] thiagodark:
did you donwload the usb drivers like guide says?! i could send you just the drivers, but i'm at work now...

did you try this?

http://xdaforums.com/showpost.php?p=14505946&postcount=321
[Nexus S General] Zorrich:
Yes I got the drivers through the program and installed as per the guide. I'm not home either, will have a look at the link you mentioned later tonight.

Cheers.
[Nexus S General] Zorrich:
That did it, thanks a bunch.
[Nexus S General] EvilSpants:
OK question has probably been asked in this forum already, and more than likely in this thread, but here goes:

Does this guide work on a Nexus S i9020a running stock Android 2.3.4? Also what are the consequences of rooting via this method? Is it correct in that I can no longer recieve OTA updates? If so, am I able to to at least manually install these updates when they are released?

I am looking to root the device when I get home tonight after work.
[Nexus S General] thiagodark:
Does this guide work on a Nexus S i9020a running stock Android 2.3.4?

A: Yes

Also what are the consequences of rooting via this method? Is it correct in that I can no longer recieve OTA updates?

A: You will receive ota uptates if you keep stock recovery, but you will lose the root after the update

If so, am I able to to at least manually install these updates when they are released?

A: Yes, as soon as ota file get posted here.

I am looking to root the device when I get home tonight after work.

A: Good luck, and if you get any issue, take a look in the last 10 pages from this thread, the answer is probably here.
[Nexus S General] NexusC:
Hey

I (think I) rooted my nexus s. But when I go in fastboot and choose recovery I dotn't seem to go into clockwork recovery. I've looked arround and flashed the recovery.img again bust still no luck.

I saw something about renaming "install-recovery.sh". I tried to do that via File expert, failed.

Any help?

Is it "dangerous" to install CyanogenRom when I'm in clockworkrecovery when i flashed it?
[Nexus S General] thiagodark:
i don't understand very well what you said, but how did you fail in rename install-recovery.sh?

when you are in bootloader and select recovery what do you see?!
[Nexus S General] zero383:
After flashing recovery don't reboot the phone, go directly into Recovery immediately after and you don't have to worry about renaming install-recovery.sh unless you want CWM to be permanent. FYI, you need root access and a program like Root Explorer in order to rename that file.
[Nexus S General] mb_:
Hi, I'd like to root Nexus S I9023XXKD1 but am not sure which ClockworkMod recovery image file to use (the original file 3024v3-i9023.img is not on mediafire any more). Could you pls direct me to the right image file to use? Thx!

[Nexus S General] NexusC:
First I wanna thank you for the replies.

When I choose recovery, I get the android with "!".

And when i try to rename the file, my file explorer (ES file explorer) I get an error.

And i didn't reboot the phone after flashing the recovery.

So CMR, doesn't have to be permanent to flash a ROM?

Can i skip the step where i should flash the superuser .zip and instead install the superuser app from the market, having the same result?

No, you must have su file, Superuser.apk is used to manage apps requiring root access.

when you are in bootloader screen and type "fastboot flash recovery ...." in cmd, wha do you get in cmd? and what do you see in phone screen?!

just copy the file to the sd card of your phone.

have you tried to make a factory reset into recovery?
[Nexus S General] criperro:
Is there any specific path where I should paste the file or can i put at the root

any path, but put in root, it's easier! if you put inside a folder, you will need to navigate in cwm....

Guys i have a few questions.....can i just install rom manager from the market and then flash clockworkmod from there?? or do i need to be rooted first to flash cwm??

Sorry for noobness....but got my nexus s yesterday and its my first android device...thanks
[Nexus S General] thiagodark:
in any android device you need to root before, rom manager asks for su permission to flash cwm..

Greetings, people. I have a nexus s i9023. I was wondering if the official Cyanogenmod rom7 supports this phone?? i have read in some other thread where someone flashed an i9020 rom to his i9023 and got bricked

I dont want a brick!! can anyone help??

thanks
[Nexus S General] thiagodark:
of course, it is supported. i don't know what was made to brick the phone in the thread you are talking about, but 9023 is as supported as 9020...
[Nexus S General] akshayf:
that's what i thought. So does that mean any rom Made for 9020 will also work on 9023??

same doubt as above

will it work on 2.3.4?

yes, it works fine with 2.3.4. this guide is quite simple, but you always can use the one-click tool, created by our friend Borky_16, just look this thread: http://xdaforums.com/showthread.php?t=1138755

guys can u suggest a good kernel to go with the official cm7 rom?? BLN support is a must...thanks
[Nexus S General] thiagodark:
all kernels supports BLN, so, it depends on what are you looking for, if you want UV, OC, Custom OC, etc...

i like matr1x, cause it's pretty close to stock, netarchy are great too has custom uv using proton app, and morfic's one is really good too. I'm currently trying james bond, and also is pretty nice.

i guess you will need to try by yourself! =o)
[Nexus S General] ciwek90:
i currently using stock rom and already flash netarchy kernel. So, if i want to try all kernel one by one what am i should do? just flash another kernel just like that? or need to wipe cache and dalvik-cache first then can flash the kernel? thanks!
[Nexus S General] afilopou:
Go to device manager,connect your phone with usb.You can see "Android phone" or something like that? What do you have under "android phone"?Android bootloader interface?

Wait a second ...you opened a cmd correct?what did you type there?You must go from cmd to the folder where fastboot is

eg C:\Program Files\Android\androidsdk\tools
[Nexus S General] Fmbl:
Hey,

Yes under android phone there is a file called Android bootloader interface!

In CMD i typed C:\Program Files\Android\android-sdk\tools but i still get the same error message!

I cant seem to figuere out where and if i go wrong!
[Nexus S General] afilopou:
Ok check the attached file with some screenshots and small instructions
[Nexus S General] Fmbl:
Hey, thnx very much for trying to help me out, thats really appreciated!

I deleted the mentioned files in tools and replaced them with the ones you send me, there was no adb.exe in tools so i copy/paste it from i believe platforms to tools dir.

It's quite strange but CMD just doesnt recognize the command im giving C:\Program Files\Android\android-sdk\tools>dir, the same error message keep coming up!

But once again thanks a lot for helping me out!

[Nexus S General] Silooy:
Can anyone confirm that Rom Manager will not work for the 9023. Since when u start up Rom manager it says u need to install clockwork 3.0.0.5. When u choose to do that your Clockwork is messed up. So for the 9023 users we have to do it like thise manual describes and no other way. So rom Manager is useless for us unless they update it with the clockwork that is being used in this thread.

Can anyone confirm this?
[Nexus S General] smoothfreeze:
I can CONFIRM this. My nexus s is now messed up after installing rom manager from the Market. My nexus s is now at Samsung for repair. :(
[Nexus S General] Bandis710:
I can confirm that rommanager can not be used .. It will indeed install a version that is not compatible with the 9023 .. I allready emailed Koush about it , but haven't gotten a reply until now ...

it didn't however mess up my phone .. Got all kinds of errors in CWM after rommanager installed the incompatibloe version .. So I just redid the procedure to flash the CWM from this thread and evrything was okay again .. But when you want to use rommanager after that it will keep saying that CWM needs to be installed so rommanager is a big no go at the moment for the 9023 users
[Nexus S General] Silooy:
ah i see. You could have fixed it yourself mate with adb. I could have explained it to you it's not that hard. You could have used fastboot and push the good clockwork on it
[Nexus S General] smoothfreeze:
Its ok, I kinda gave up on this after watching the Google logo stuck on my phone til the battery died. :eek: Think I'm gonna wait for a "One Click" root for the Nexus S, just like iPhone jailbreaks...

haha yeah i had that 2 but it's a easy fix. Just give me a pm if u still wanna give it a go when u get your phone back
